Kurt Russell says the whole ending of 'Fast and Furious 7' is being changed in the wake of Paul Walker's death.

The film franchise's star was killed in a horrific accident on November 30 when the car Paul was travelling in careered off the road and smashed, which has led to his final film - which was incomplete at the time - being significantly altered.

Kurt - who is joining the franchise playing a father figure to Vin Diesel's character - told ETonline.com: ''They're having to rewrite, they're having to do whatever they're having to do to deal with the situation.

''Listen, it's catastrophic. It's the worst thing that could happen to a movie, but it's not as bad as what happened to Paul. So everything is in perspective. He was a terrific guy. And life is full of curveballs.''

The 62-year-old star added the fate of his own character may now change in the new ending.

He added: ''Whether or not this guy dies off in the movie, we don't know, and that may have changed now significantly, too.''

It has previously been claimed Paul's character - undercover police officer Brian O'Connor - will not be killed off in the movie and will instead be written out of the script using existing footage of Paul in a bid to keep fans satisfied and allow for the franchise to continue in future.
